As a designer you need to understand aspect ratios dude! Nearly every monitor is 16:9 which means for every 16 horizontal pixels there are 9 vertical! Some Mac monitors are 16:10 and so are some laptops so there worth sometimes uploading in. Also there are 21:9 monitors so if your looking at a longer wallpaper go for something 21:9 like 2556X1080 and for 16:9 1920X1080! 1920X1080 will fit great onto most netbooks laptops and desktops without any black bars or cropping. Thanks for reading this cause I love your wallpapers but I can't use them on my monitor due to there low res or wierd aspect ratio. ~Derpydeponson

Hmm, yeah everyone's been saying I need to use 1920x1080 not 1920x1200, but I always thought using 1920x1200 means that 16:9 and 16x10 can both use the wallpaper. Thanks for the tip, I'll make em in 1920x1080 now. I haven't made any for ages cause of GCSE's, but they're over in 10 days so then I'll have all of summer.
